I believe these guys can set you up with a daughterbord for that ECU.

Hello Joe:

I have a 4AG powered Toyota Corolla, a 1985 GTS. After followinh your advice and contacting Technosquare they mentioned that I needed to bring the car to their location in California in order to tuned(burn chip in a try and error mode) the car.

For some of us that is really not an option. Is there a true plug-n-play ECU that could fit inside our original housing? I know of at least a few stand alone systems that could sell their product in a plug-n-play
application for just about any car (i.e. HYDRA EMS).

Thanks,
